PHP does not have MySQL support when the alternative _php Foundation

The General Personal free homepage space will not provide MySQL support, is to provide also very harsh, so looking for a good alternative is very important oh!
PHP's file processing is very powerful, so you can use file access to replace it!
(To know when there is no database, everything is organized with files!) Oh! , where the data items are separated by special symbols, I am using "| |" to facilitate the reading of a single record through the Explode () function!
In fact, the idea of the database here is still available! Like the index of the database!
So you have to do an index file first! (That's not true)
Let's leave a message for this:
The main documents are:
Index.database
The structure is as follows:
Message Person Name | | Message Person Sex | | Message Time | | Message Content Storage Location | | Feiyn (This is easy to read when the ' n ' Jerky!)
Each store row can be easily read through the PHP fgets () function, or the file () function reads each row to the array
In order to prevent multiple people from writing to the data conflict, it is also necessary to lock (also implemented by file)
Here is the write code
<?php
The following parameters must be passed in:
Message person name $name
Message Person Gender $sex
Message Time $time
Message Content Location $savePosite
$indexFile = "Index.database";
$indexFileLock = $indexFile. " Lock ";
$message = $name. "| |" $sex. "| |" $time. "| |" $savePosite. "| | feiy| | ";/ /This is the record to write
while (File_exists ($indexFileLock)) $temp + +; Detect if lock has been added
Fclose (fopen ($indexFileLock, "w")); If no, enter and lock to avoid the same access violation
$FP =fopen ($indexFile, "a");
Fputs ($message, strlen ($message));
Fclose ($FP);
Unlink ($indexFileLock);//unlock
?>
Reading code
<?php
$indexFile = "Index.database";
$indexFileLock = $indexFile. " Lock ";
while (File_exists ($indexFileLock)) $temp + +; Detect if lock has been added
Fclose (fopen ($indexFileLock, "w")); If no, enter and lock to avoid the same access violation
$ary =file ($indexFile);
Unlink ($indexfileLock);//unlock
for ($i =0; $i <sizeof ($ary); $i + +) {
$tempAry =explode ("| |"), $ary [$i]);
Echo ("Name:". $tempAry [0]);
Echo ("Sex:". $tempAry [1]);
Echo ("Sex:". $tempAry [2]);
Echo ("Saveposite:", $tempAry [3]);//You can read the message from this address
}
?>

Through the above can easily solve the common use of web pages, such as chat rooms, BBS forums, bookmarks and so on
If the prawn has a better solution, please enlighten me! Thank you!
